STEM WINDIG AND SETTING MECHANISM.

SPECIFICATION forming part of Letters :Patent No. 468,204, datedFebruary 2, 1892.

Application filed April 14,1891. Serial No. 388,856. (No model.)

' ant-setting attachment for watches, and has for its object to providea winding-pinion capable of both a rotary and end movement and soconstructed as to remain in gear withthe crown-wheel in any position;also, to provide a means whereby the winding stem or arbor may beexpeditiously and conveniently attached to the winding-pinion and t-o soconstruct the entire mechanism that the pendant-setting is operatedindependent of any attachment in the case and can be attached to anyordinary winding stem or arbor, such as commonly used in stem-windingwatchcases.

The invention consists in the novel construction and combination of theseveral parts, as will be hereinafter fully set forth,` and pointed outin the claims.

Reference is to be had to the accompanying drawings, forming a part ofthis speciication, in which similar Iigures of reference indicatecorresponding parts in all the views.

Figure 1 is a plan view of the front plate of a movement illustratingthe application of the invention and showing 'the winding-pinion in aposition to cause movement of the winding-drum. Fig. 2 is a similar Viewto that illustrated in Fig. 1, the winding-pinion, however, being inposition to cause move' ment of the hands. Fig. 3 is a vertical sectiontaken practically on the line 3 3 of Fig. l. Fig. 4 is a verticalsection taken through the winding-pinion and illustrating the attachmentthereto of the winding stem or arbor. Fig. 5 is a bottom plan View ofthe shifting-lever, and Fig.` G is a bottom plan View of thecrown-wheel.

The winding-pinion A is provided with a pivot 10 at one en d, whereby itis journaled in its seat in the movement, and in the opposite or outerend of the pinion a socket is produced, pre terably rectangular orpolygonal in cross-section. Upon the outer surface of the pinion at ornear its lower end longitudinal teeth 12 are formed, and at or near thecenter of the periphery an annular groove 13 is produced. The pinion isfurther provided between its groove 13 and its upper end with a threadedaperture leading into the socket and adapted for the reception of a setor binding screw 14. The socket of the pinion is adapted for thereception of the squared end 15a of the usual form of winding arbor orstem 15, and the inserted end of the stem or arbor is provided with arecess, into which the binding-screw 14 enters. Through the medium ofthe screw the pinion maybe revolved by turning the stem or moved endwiseby manipulating the stem in that direction. The pivot of the pinion isof sufficient length to remain in its'bearing, even when the pinion iscarried outward to its full extent, and consequently when the pinion isin this position it may be revolved with as much steadiness as when inits innermost position.

The'crown-Wheel 16, which meshes with the teeth of the winding-pinion,is, in addition to the usual teeth 16a, provided with peripheralhorizontally-disposed teeth 17. The crownwheel is held to revolve in aspring-pressed yoke 18, pivoted at one end upon the front plate 19 ofthe movement, which yoke also carries a shifting pinionV 20. Theshifting pinion is in constant engagement with the teeth 17 of thecrown-wheel, and the regular teeth 16n of said wheel, as heretoforestated, constantly mesh with the teeth upon the winding-pinion, whethersaid pinion'isin its outer or in its inner position.

The shifting pinion 2O is located between a train of gearing 21, adaptedto convey movement to the hand staff or spindle of the watch and thegear 22 of the winding-drum, and is in engagement either with one or theother, according to the position ot the windingpinion.

A shifting-lever 23 is pivoted upon the front plate over the yoke andengages at one end with the free extremity of the yoke, and near itsopposite end the lever is provided with a pin 24, adapted topass throughan aperture in the front plate of the movement and enter the groove 13of the Winding-pinion.

.The inner position of the winding-pinion is the normal one, and' whenthe pinion is in this position the lever 23 bears loosely upon the yoke,as shown in Fig. 1, and the shifting pinion 2O is in engagement with thegear 22 of the winding-drum. vVhen the winding arbor or stem is drawnoutward, the windingpinion is carried to its outer position, and theupper end of the lever 23 is carried with it, and the upper extremity ofthe lever, engaging with the ilange of the front plate, limits theoutward movement of the pinion, while the innerend of the lever, whichacts as a dog, forces the yoke downward and enters the recess in theyoke, holding the latter in position to cause the shifting pinion tomesh with the train of gearing 2l, whereby when the arbor l5 is revolvedthe hands will be turned. By pushing the arbor inward the yoke isrestored to its normal position and the shifting pinion is brought inmesh with the drum-gear and the watch is in condition to be wound.

The lever illustrated at the right ot' the stem-winding mechanismconstitutes no portion of the invention, and is merely intended to showthat the watch can be used as a lever-set, if desired.

It-is evident that one of the main features ot the improved.pendant-setting is that it is interchangeable and can be used on eitheran open-face or hunting-case watch-movement without any change in theconstruction of its parts.

Having thus described my invention, I claim as new and desire to secureby Letters Patentf l. In a pendant setting attachment for watches, thecombination, with a crow n-wheel and shitting pinion, of awinding-pinion having a rotary and endwise movement and meshing at alltimes with the crown-wheel, substantially as described.

2. In a pendant setting attachment for watches, the combination, with acrown-wheel and ashifting pinion meshing with the crownwheel, of awinding-pinion having a rotary and endwise movement and meshing at alltimes with the crown-wheel, and mechanism for moving the shifting pinionfrom the winding-pinion, substantially as described.

3. In a pendant-setting attachment for watches, the combination, with acrown-wheel, a pivot-ed yoke, and a shitting pinion meshing with thecrown-wheel, of a winding-pinion having a rotary and endwise movementand meshing at all times with the crown-wheel, and a shifting-leverengaging the yoke and winding-pinion, substantially as and for thepurpose set forth.

4. In a pendant-setting attachment for watches, the combination, withthe setting and winding gear, of a pivoted yoke, a shifting pinionmounted in the yoke, a crownwheel with which the shifting pinion meshes,a winding-pinion having a rotary and endwise movement and meshing withthe crownwheel at all times, and mechanism for moving the yoke by theendwise movement of the winding-pinion, substantially as described.

5. In a pendant-setting attachment for watches, a winding-pinionprovided with a socket at one end', a bindin g-screw atitssocket end, apivot at its opposite end, peripheral teeth near the trunnion, and agroove betweenthe teeth and the binding-screw, as and for the purposeset forth.

G. In a pendant-settingfor watches, the-coinbination, with awinding-pinion provided with a pivot at one end, a socket at theopposite end, peripheral teeth near the trunnion, a binding-screw at thesocket end, an annular groove between the binding-screw and teeth, and awinding arbor or stem, one end of which is inserted in thepinion-socket, the said inserted end being recessed to receive thebinding-screw, of a spring-pressed yoke carrying' a shifting pinion, anda shifting-1ever provided with a pin entering the groove of thewinding-pinion, the said shifting-lever being in engagement with theyoke, as. and for the purpose specified.
